**body:**

(a) MRO appointment. Each operator shall designate or appoint a medical review officer (MRO). If an operator does not have a qualified individual on staff to serve as MRO, the operator may contract for the provision of MRO services as part of its anti-drug program.

(b) MRO qualifications. The MRO must be a licensed physician with knowledge of drug abuse disorders.

(c) MRO duties. The MRO shall perform the following functions for the operator:

(1) Review the results of drug testing before they are reported to the operator.

(2) Review and interpret each confirmed positive test result as follows to determine if there is an alternative medical explanation for the confirmed positive test result:

(i) Conduct a medical interview with the individual tested.

(ii) Review the individual's medical history and any relevant biomedical factors.

(iii) Review all medical records made available by the individual tested to determine if a confirmed positive test resulted from legally prescribed medication.

(iv) If necessary, require that the original specimen be reanalyzed to determine the accuracy of the reported test result.

(v) Verify that the laboratory report and assessment are correct.

(3) Ensure that an employee has been drug tested in accordance with the DOT Procedures before the employee returns to duty.

(d) MRO determinations. The following rules govern MRO determinations:

(1) If the MRO determines, after appropriate review, that there is a legitimate medical explanation for the confirmed positive test result other than the unauthorized use of a prohibited drug, the MRO is not required to take further action.

(2) If the MRO determines, after appropriate review, that there is no legitimate medical explanation for the confirmed positive test result other than the unauthorized use of a prohibited drug, the MRO shall refer:

(i) The individual tested to a personnel or administrative office for further proceedings in accordance with the operator's anti-drug plan; and

(ii) For evaluation by a SAP who shall determine what assistance, if any, the employee needs in resolving problems associated with drug misuse.

(3) Based on a review of laboratory inspection reports, quality assurance and quality control data, and other drug test results, the MRO may conclude that a particular drug test result is scientifically insufficient for further action. Under these circumstances, the MRO should conclude that the test is negative for the presence of a prohibited drug or drug metabolite in an individual's system.

(e) Evaluation and rehabilitation may be provided by the operator, by a substance abuse professional under contract with the operator, or by a substance abuse professional not affiliated with the operator. The choice of substance abuse professional and assignment of costs shall be made in accordance with the operator/employee agreements and operator/employee policies.

(f) The operator shall ensure that a substance abuse professional, who determines that a covered employee requires assistance in resolving problems with drug abuse, does not refer the covered employee to the substance abuse professional's private practice or to a person or organization from which the substance abuse professional receives remuneration or in which the substance abuse professional has a financial interest. This paragraph does not prohibit a substance abuse professional from referring a covered employee for assistance provided through:

(1) A public agency, such as a State, county, or municipality;

(2) The operator or a person under contract to provide treatment for drug problems on behalf of the operator;

(3) The sole source of therapeutically appropriate treatment under the employee's health insurance program; or

(4) The sole source of therapeutically appropriate treatment reasonably accessible to the employee.
